The weather predictions for Asia in 2050 read like a story from a doomsday movie.
Many experts and green groups fear they will come true unless there is a united global effort to hold back greenhouse gas outpouring. In the decades to come, Asia---home to more than half the world’s 63 billion people-will change from one climate extreme to another, with tired farmers battling droughts, floods, disease, food shortages and rising sea levels.
“It’s not a pretty picture,” said Steve Sawyer, climate policy adviser with Greenpeace in Amsterdam. Global warming and changes of weather patterns are already occurring and there is more than enough carbon dioxide and other greenhouse gases in the atmosphere to drive climate change for decades to come.
Already, changes are being felt in Asia but worse is likely to come, Sawyer and top climate bodies say, and could lead to mass migration and widespread human disasters. According to predictions, icebergs will melt faster, some Pacific and Indian Ocean islands will have to evacuate(疏散) or build sea defenses, storms will become more intense and insect and water-borne diseases will move into new areas as the world warms.
All this comes with rising populations and demand for food, water and other resources. Experts say environmental worsening such as deforestation and pollution will probably enlarge the results of climate change.
In what could be a sign of the future, Japan was hit by a record of 10 typhoons and tropical storms this year, while two-thirds of Bangladesh, parts of Nepal and large areas of northeastern India were flooded, affecting 50 million people, destroying livelihoods and making tens of thousands ill.
The year before, a winter cold struck and a summer heat wave killed more than 2,000 people in India.

Rising levels of carbon dioxide in the atmosphere are a major cause of climate change, and now a new study has confirmed that atmospheric CO2 is also affecting the ocean chemistry and potentially harming sea life.
Montana State University scientist Robert Dore has been researching the water in the Pacific Ocean for almost two decades. "We've been going to the same spot in the Pacific Ocean, and we try and characterize long-term change in the open ocean environment. And one of the key things that we measure is COx levels. And We've been able to record this increasing quantity of atmospheric CO, into the ocean. "Scientists expected that as atmospheric CO2 increased, more and一 more of the carbon dioxide would be absorbed into the ocean, affecting the chemical balance of the sea water, with a potentially harmful impact on shellfish and coral in particular.
"As carbon dioxide dissolves in the water, or seawater in this case, it forms a weak acid, carbonic acid," Dore explains. "And therefore, as the concentration of CO2 in the atmosphere goes up and that exchanges with the surface seawater, it drives the pH down, and makes it more acidic."
The seawater samples Dow and his colleagues have analyzed confirm what the theory predicts. The effect was particular striking at about 250 meters down, and again at 500 meters. Dore and his colleagues came up with two possible explanations. It could be that surface water picked up CO2 and then moved to those depths. Or there could be a biological explanation.
"It's important to realize that the oceans are really becoming acidic. And it can have negative impacts on a whole variety of sea life from fish to coral. It’s potentially catastrophic."

Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US.
When 40 per cent of Hawaii's US$14 million-a-year papaya (木瓜)industry was destroyed by a virus five years ago, work began on creating genetically engineered(转基因的)trees.
Researchers successfully introduced seeds that were designed to resist the virus.Since then, more and more people have been testing genetically engineered trees.Some researchers put special bacteria into trees to help them grow faster and produce better wood.Others are trying to create trees that can clean polluted soil.Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper.
The Pentagon (五角大楼) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack.So far, the poplar, eucalyptus (杨树与桉树), apple and coffee trees are among those being engineered.All this can be done today because we have a better understanding of tree genomes (基因组).
However, some people fear that the genetically engineered trees will cause dangerous results.They are worried that the new trees will breed with natural species and change the balance of the forest environment.
“It could be destructive,” said Jim Diamond, an environmentalist. “Trees are what is left of our natural environment and home to many endangered species.”
But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.
【小题1】Which kind of tree is not the ones that scientists are planting in the US?
A.Trees that worms can't hurt. |
B.Genetically engineered trees. |
C.Trees that can resist wind better. |
D.Trees that can protect themselves at a chemical attack. |
A.Tree genomes are mapped out so scientists know how to improve trees. |
B.Great numbers of trees have been lost due to attacks by viruses. |
C.Researchers successfully introduced seeds designed to resist the virus. |
D.They think science could give nature a fighting chance against both natural and man-made dangers. |
A.Papaya. | B.Pine. | C.Apple. | D.Poplar. |
A.these trees can destroy the balance of nature |
B.everything except trees has been genetically engineered |
C.trees are home to many endangered species |
D.these trees may affect normal trees |

It's a fact that we all dream. Some dreams seem to last for hours, others only for seconds. Some of us have strange dreams, some have interesting dreams, and some of us have unpleasant dreams. Tests in the 1980s showed that these dreams occur within 90-minute cycles, each cycle made up of six stages. In the last stage people experience rapid eye movement, known as REM, and it is in this stage that dreaming takes place. Eighty percent of people who were woken during this sixth stage could easily remember their dreams. On the other hand, when during the first five stages (NREM), only seven percent could describe a dream.
However, of these same people woken during the first five stages, 74% were able to remember thinking activity, although they would not call it a dream. NerysDee, who has written about dreams in a book called "Your Dreams and What They Mean" says: "Perhaps during NREM sleep we are sorting out our outer mundane problems, but in REM sleep we are dealing with inside matters." She also makes the following statement about 90-minute cycle: It may also prove the reason why insomniacs who wake in the middle of the night find it impossible to get to sleep again for at least an hour and a half. In other words, until they have missed out one complete 90-minute sleep period.
【小题1】Which of the following statements about dreams is TRUE?
A.Everyone dreams but very few can recall what they dream. |
B.Some people have long dreams and others have very short ones. |
C.People can only remember unpleasant dreams. |
D.More than eighty percent of people can remember their dreams. |
A.between each 90-minute cycle |
B.at any time during 90-minute cycles |
C.during the first five stages of 90-minute cycles |
D.in the last stage of 90-minute cycles |
A.hardly remember their dreams |
B.easily remember their dreams |
C.only remember their dreams |
D.partly remember their thinking activity |
A.can always remember their dreams |
B.have trouble getting into sleep at night |
C.experience rapid eye movement |

When Hurricane Phailin hit India in late 2013, it became the largest storm to strike the subcontinent in over a decade. The storm affected more than 12 million people in India and neighboring countries, and damaged or destroyed many houses. However, good news is that cleverly-designed beach house created by architect Ray Huff can survive such strong winds and storm waves.
Located on the shore of an Indian island, Huff’s award-winning cube-shaped beach house was built to replace one smashed to pieces by Hurricane Phailin.
Huff pointed out that many houses built along shoreline were poorly constructed, and enforcement(执行) of building codes wasn’t strict. After Phailin’s attack, all new shoreline houses are required to meet stricter, better-enforced codes. The new beach house should be able to stand a Category 3 hurricane with peak winds of 179 to 209 kilometers per hour.
At first sight, Huff's house looks anything but hurricane-proof. Its redwood shell makes it resemble “a large party lantern” at night, according to one observer. But looks can be misleading. The house’s wooden frame is reinforced(加固) with long steel rods to give it extra strength.
To further protect the house from hurricane damage, Huff raised it 2.7 meters off the ground on pilings---long columns of wood anchored(固定) deep in the sand. Pilings might appear insecure, but they are strong enough to support the weight of the house. They also balance the house above storm waves. The pilings allow the waves to run under the house instead of running into it. “These swells of water come ashore at great speeds and cause most of the damage done to beach-front buildings,” said Huff.
Huff designed the wooden pilings to be partially hidden by the house’s ground-to-roof shell. “The shell masks the pilings so that the house doesn’t look like it’s standing with its pant legs pulled up,” said Huff. In case of a storm wave, the shell should break apart and let the waves rush under the house, the architect explained.
【小题1】After Hurricane Phailin, new houses built along shore line are required_____.
A.to be easily reinforced |
B.to look smarter in design |
C.to meet stricter building standards |
D.to be designed in the shape of cubes |
A.it is made of redwood |
B.it is in the shape of a shell |
C.it is strengthened by steel rods |
D.it is built with wood and stones |
A.support the weight of the house |
B.allow the waves to run through the house |
C.anchor stronger pilings deep in the sand |
D.prevent water from rushing into the house |
A.to give the house a better appearance |
B.to strengthen the pilings of the house |
C.to protect the wooden frame of the house |
D.to slow down the speed of the swelling water |

Do you like seahorses? What do you know about them?
The seahorse is actually not a horse but a fish, and much smaller than any regular horse. In general, a seahorse is about an inch long. It is a beautiful fish that likes warm waters, swims upright (直立的), and looks a little like a chess piece.
Seahorses are an unusual kind of animal because the males (雄性) give birth to babies. Mating (交配) takes place in cooler waters on spring and summer nights with a full moon. The females (雌性) put their eggs into the bodies of the males, and the males give birth to baby seahorses.
The seahorse can use each eye separately, which allows it to search for food without moving the rest of its body. Seahorses situate themselves near deep, fast-running channels rich in plankton, a kind of life on which they feed. They can catch food from an inch and a half away. Seahorses can change from gray or black to yellow or purple within seconds to fit in with their surroundings, and in this way escape from most of their enemies.
One of the surprising facts about seahorses for most people is that they are vertebrates (脊椎动物). They can turn and curl freely, and like to swim in pairs connected by their tails. Their tails are powerful, and they can use them to grasp the surrounding seaweed (海藻) to keep themselves from being swept away. So seahorses are usually found in warm water filled with seaweed.
Now that you know all these facts about seahorses, don’t you find them more interesting?
【小题1】We can learn from the passage that seahorses _______.
A.are beautiful, and live on seaweed |
B.are as big as regular horses |
C.live near deep channels |
D.like to be alone |
A.male seahorses lay eggs |
B.seahorses mate in spring or autumn |
C.male seahorses give birth to babies |
D.seahorses mate in warmer waters at night |
A.Their fast speed of swimming. |
B.Their ability to change colours. |
C.Their unique eyes. |
D.Their strong tails. |
A.Eat. | B.Hold. | C.Make. | D.Handle. |

You can’t always predict a heavy rain or remember your umbrella.But designer Mikhail Belyaev doesn’t think that forgetting to check the weather forecast before heading out should result in you getting wet.That’s why he created Lampbrella,a lamp post with its own rainsensing umbrella.
The designer says he come up with the idea after watching people get wet on streets in Russia.“Once,I was driving on a central Saint Petersburg street and saw the street lamps lighting up people trying to hide from the rain.I thought it would be appropriate to have a canopy(伞篷)built into a street lamp,”he said.
The Lampbrella is a standardlooking street lamp fitted with an umbrella canopy.It has a builtin electric motor which can open or close the umbrella on demand.Sensors(传感器)then ensure that the umbrella offers pedestrians shelter whenever it starts raining.
In addition to the rain sensor,there’s also a 360°motion sensor on the fiberglass street lamp which detects whether anyone is using the Lampbrella.After three minutes of not being used the canopy is closed.
According to the designer,the Lampbrella would move at a relatively low speed,so as not to cause harm to the pedestrians.Besides,it would be grounded to protect from possible lightning strike.Each Lampbrella would offer enough shelter for several people.Being installed(安装) at 2 meters off the ground,it would only be a danger for the tallest of pedestrians.
While there are no plans to take the Lampbrella into production,Belyaev says he recently introduced his creation to one Moscow Department,and insists his creation could be installed on any street where a lot of people walk but there are no canopies to provide shelter.
【小题1】For what purpose did Belyaev create the Lampbrella?
A.To predict a heavy rain. |
B.To check the weather forecast. |
C.To protect people from the rain. |
D.To remind people to take an umbrella. |
A.His creation was inspired by an experience. |
B.It rains a lot in the city of Saint Petersburg. |
C.Street lamps are protected by canopies. |
D.He enjoyed taking walks in the rain. |
A.motor→canopy→sensors |
B.sensors→motor→canopy |
C.motor→sensors→canopy |
D.canopy→motor→sensors |
A.Its moving speed. |
B.Its appearance. |
C.Its installation. |
D.Its safety. |
A.The designer will open a company to promote his product. |
B.The Lampbrella could be put into immediate production. |
C.The designer is confident that his creation is practical. |
D.The Lampbrella would be put on show in Moscow. |

(2013·高考北京卷,D)People who multitask all the time may be the worst at doing two things at once,a new research suggests.The findings,based on performances and selfevaluations by about 275 college students,indicate that many people multitask not out of a desire to increase productivity,but because they are easily distracted (分心) and can’t focus on one activity.And “those people turn out to be the worst at handling different things,”said David Sanbonmatsu,a psychologist at the University of Utah.
Sanbonmatsu and his colleagues gave the students a set of tests and asked them to report how often they multitasked,how good they thought they were at it,and how sensationseeking (寻求刺激) or impulsive (冲动)they were.They then evaluated the participants’multitasking ability with a tricky mental task that required the students to do simple mathematical calculations while remembering a set of letters.
Not surprisingly,the scientists said,most people thought they were better than average at multitasking,and those who thought they were better at it were more likely to report using a cellphone while driving or viewing multiple kinds of media at once.But those who frequently deal with many things at the same time were found to perform the worst at the actual multitasking test.They also were more likely to admit to sensationseeking and impulsive behavior,which connects with how easily people get bored and distracted.
“People multitask not because it’s going to lead to greater productivity,but because they’re distractible,and they get sucked into things that are not as important,”Sanbonmatsu said.
Adam Gazzaley,a researcher at the University of California,San Francisco,who was not a member of the research group,said one limitation of the study was that it couldn’t find out whether people who start out less focused tend toward multitasking or whether people’s recognizing and understanding abilities change as a result of multitasking.
The findings do suggest,however,why the sensationseekers who multitask the most may enjoy risky distracted driving.“People who are multitasking are generally less sensitive to risky situations.”said Paul Atchley,another researcher not in the group.“This may partly explain why people go in for these situations even though they’re dangerous.”
【小题1】The research led by Sanbonmatsu indicates that people who multitask________.
A.seek high productivity constantly |
B.prefer handling different things when getting bored |
C.are more focused when doing many things at a time |
D.have the poorest results in doing various things at the same time |
A.assessed the multitasking ability of the students |
B.evaluated the academic achievements of the students |
C.analyzed the effects of the participants’tricky mental tasks |
D.measured the changes of the students’understanding ability |
A.limited power in calculation |
B.interests in doing things differently |
C.inability to concentrate on one task |
D.impulsive desire to try new things |
A.drive very skillfully |
B.go in for difficult tasks |
C.fail to react quickly to potential dangers |

Jerry Morris died on 28 October 2009. He was 99 years old. You have probably never heard of him. He was a professor of public health. More than 50 years ago he produced one of the most famous epidemiological (流行病学) papers of the 20th century.
His study showed that bus conductors were much less likely to die of heart disease than bus drivers. Why? Because the conductors spent their working day walking. It seems obvious now but in the middle of the last century doctors were puzzled by the rising numbers of people who got heart diseases. Jerry Morris found one of the main causes: a sedentary (久坐不动的) lifestyle. He started exercising for a few minutes each day and lived until his 100th year.
If you wish to protect your heart, you have to do more than wander in the garden. The exercise needs to be reasonable. Jogging is not for everyone and a round trip to the gym takes a couple of hours, plus the monthly membership fee is only good value if you visit regularly. The answer is simple: walk.
A half-hour purposeful walk five times a week will lower your risk of heart disease, diabetes and strokes. Older people sometimes feel they have left it too late. But it is never too late to start and there are no upper age limits. Start gently. Take your time: a 15-minute flat walk in the nearest park, four or five times a week. Within a month or so, you are already beginning to protect your heart. Build the walks up. When you can comfortably walk for half an hour in the park, go further: try following rivers and canals.
Regular walkers have their own natural gymnasium. There is no membership fee, just some of the finest scenery in the world. Great Britain is the walker’s gym. When you have followed the rivers and canals, and are enjoying walking for a couple of hours, head for the coast. Once again, build it up slowly. When you are comfortable with long coastal walks, you can think of our national parks.
【小题1】Jerry Morris is mentioned in the first paragraph mainly to __________.
A.make his epidemiological message known to the public |
B.praise his research into ways of improving public health |
C.introduce the topic of doing exercise and keeping healthy |
D.give an example of a person who lives a healthy and long life |
A.bus conductors are more likely to die of heart disease than bus drivers. |
B.doctors in the 1950s knew why heart diseases kept happening to people. |
C.walking is better than doing sports in a gym because it saves time and money. |
D.British people love walking because they have free gymnasium with finest scenery. |
A.Parks are the best place for walking. |
B.Starters should not push themselves too hard. |
C.A two-quarter walk a day is suitable for starters. |
D.People of old age might not be fit enough to start walking. |
A.Long Life Comes from Walking |
B.Walking Helps Cure Heart Disease |
C.A Walk a Day Keeps the Doctors away |
D.An Hour’s Walk in Nature is Worth Two in the Gym |
